To all whom it may concern.- l

Beit knownthat I, J AJimsPnEsToNll/IAUZEY, l.

of' Blackfoot, in the county of- Deer Lodge and Territory of Montana, haveinvented a new lar heater. Fig. 2 is' a vertical section of' the same. Fig. Sis anend viewin smallersiie. Figs. et, 5, and 6 represent reflectors in difieren ti'orms. Fig. 7 represents a bar made use of to elevate and sustain the swinging frame.

Similar letters of reference indicate corre- A 1s the supporting-base,"consisting oi' aY rectangular wood or metal frame. mounted on wheels or rollers et. B is the reflector-carrying frame, sustained upon the base A by the side arms, b, that are piv'eted at c. Upon each side of A is attached a semicircular brace, d, perforated with numerous holes corresponding to holes in the arms b, so that by the insertion of a pin the arms b and frameB are sustained atthe desired inclination. The arms b and frame B are united by means of sockets e, that are attached to B and set over b, and are retained in place by pinspassing through holes,

' so that the frame B can be raised and lowered.

constructed of metal or wooden rods,'to which the reflectors are detachably connected, so that they can be removed or adjusted.

y The reflectors are made in two shapes-one shape (shown in Fig. 4 at f) being concave, and the other, Fig. 5, curved or concave in one direction only. The last-named shape may be considered as a section of an elliptical cylinder, as

:represented in Fig. 6, and the reflector may be a full quadrant of the ellipse or any portion of the same, the concavity being regulated by "fthe distance the reflectors are'placed from the object to'be heated and theirrelative position therewith, and in some cases it may be desirable to vary the concavity in each reilector, the` rule in all cases being thatthe concavi'ty should decrease in proportion to the distance from the object, and the concavity in all cases should be a quadrant or part o'f a quadrant of an ellipse. By this shape and construction there- 'iiectors will focus the rays on a straight line.

The reflector shown in Fig. d, atf, will cou- Vey the rays to a point. wiseis in the are of a circle, and erosswise in the arc of an ellipse. for the ends and corners of frame B, the others being for the sides.

Fonincreasng thaextent oftheside reflecting-surface the frame B is fitted with sockets for sustaining the rods oi an auxiliary frame, g, carrying reflectors It.

At the center of the frame B are sustained, by rods passing to the corners oi'` the main frame, Vone or-more smaller reilectonirames, ft', that are fitted with their straight side reiiect ors, il', and curved end reflectors, i", hung to focus upon the object to be heated.`

In use the swinging frame B must always vbe directed to the sun, and by the above-de scribed construction this may be accomplished with great facility. Supposing the apparatus standing with the end oi'. frame A north and south; the arms b vertical, 'and the sun at the meridian, the focus of the rays should then-be upon the object; but as the sun mot/.es 'west the focus would shift to the side of the obje-ot, and it would be necessary to swing the frame B on the axis c to retain the focus at the proper place, and the frame is to be thus moved at- 'intervals and held in p lace by the devices before described, and the whole apparatus may be movedA on the supporting-rollers for perfectly accurate adjustment.

From the different positions that the reflect ors will be placed in by the east and west ad justment the position of the'focus is liable to be changed either short of or beyond the ob ject to be heated. This defect may be readily remedied by raising and lowering the frame B on its supporting-arms 1), and to. assist this operation l provide a forked bar, k, (see Fig. 7,) which is to be used as a lever by applicalts coi'lcavity length-A This `form is intended IOO tion of its forked ends tothe pins Zon sockets e, anda suitable fulcrum, as illustrated by dotted lines in Fig. 2.

The mechanism for raising, lowering, and sustaining the frame-B may be of any suitable character. The construction shown is adapted for light-apparatus; but with large heaters, requiring considerable power for their manipulation, other' mechanism such as coggedgearing and cranks-may be used.

The reectors are to be made of glass or sheet metal, and in one or more pieces, as most convenient. The apparatus is valso tted'with curtains m, of non-transparent material, hung on rollers at one or more sides of the frame B. These curtains are intended for being drawn over the 'top of the reiiectors to shut oi' the rays of the sun when desired.

The above-described solar heater is a 'convenient and effective means for utilizing the heat of the sun Afor any desired purpose. The

, rays oi' the sun are gathered from'an extensive arca and'concentrated in a most eii'ective manner upon the desired object, and the adjustmentcan be made with facility.

' Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a solar heater, the pivoted arms b and sockets e,- in combination with the baseAand reiiector-frame B, substantially as and for the purpose specified.

2. In a solar heater, the adjustable reiiector-holding frame B, formed with sides having' -reiiectors, t", attached to frame B, substantially as and for the purposes setforth. l

5. In a solar heater, the rolling curtains m, in combination with. the reflectors on frames B t', substantially as and for the purposes de- A scribed.
